Interface Configuration Mode Commands
Use the interface configuration mode for setting, viewing, and testing the configuration of WAAS software features on a specific interface. To enter this mode, enter the interface command from the global configuration mode. The following example demonstrates how to enter interface configuration mode:
GigabitEthernet Select a gigabit ethernet interface to configure
InlineGroup Select an inline group interface to configure
PortChannel Ethernet Channel of interfaces
WAE(config)# interface gigabitethernet ?
<1-2>/ GigabitEthernet slot/port
WAE(config)# interface gigabitethernet 1/0
To exit interface configuration mode, enter exit to return to global configuration mode:
(config-if) autosense
To enable autosense on an interface, use the autosense interface configuration command. To disable this function, use the no form of this command.
autosense
Syntax Description
This command has no arguments or keywords.
Defaults
Autosense is enabled by default.
Command Modes
interface configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Cisco router Ethernet interfaces do not negotiate duplex settings. If the WAAS device is connected to a router directly with a crossover cable, the WAAS device interface must be manually set to match the router interface settings. Disable autosense before configuring an Ethernet interface. When autosense is on, manual configurations are overridden. You must reboot the WAAS device to start autosensing.
Examples
The following example disables autosense on Gigabit Ethernet port 1/0:
WAE(config)# interface GigabitEthernet 1/0
WAE(config-if)# no autosense
The following example reenables autosense on Gigabit Ethernet port 1/0:
WAE(config)# interface GigabitEthernet 1/0
WAE(config-if)# autosense

(config-if) bandwidth
To configure the link speed on a network interface, use the bandwidth interface configuration command. To restore default values, use the no form of this command.
bandwidth {10 | 100 | 1000}
Syntax Description
10 |
Sets the link speed to 10 megabits per second (Mbps). |
100 |
Sets the link speed to 100 Mbps. |
1000 |
Sets the link speed to 1000 Mbps. This option is not available on all ports and is the same as autosense. |
Defaults
No default behaviors or values
Command Modes
interface configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
To configure the link speed of a network interface on a WAAS device, use the bandwidth interface configuration command. The speed is specified in megabits per second (Mbps). The WAAS software automatically enables autosense if the speed is set to 1000 Mbps.
You can configure the Gigabit Ethernet interface settings (autosense, link speed, and duplex settings) if the Gigabit over copper interface is up or down. If the interface is up, it applies the specific interface settings. If the interface is down, the specified settings are stored and then applied when the interface is brought up. For example, you can specify any of the following commands for an Gigabit over copper interface, which is currently down, and have these settings automatically applied when the interface is brought up.
WAE(config-if)#
bandwidth 10
WAE(config-if)#
bandwidth 100
WAE(config-if)#
bandwidth 1000
WAE(config-if)#
autosense
WAE(config-if)#
half-duplex
WAE(config-if)#
full-duplex
Note We strongly recommend that you do not use half-duplex connections on the WAE or on routers, switches, or other devices. Use of half-duplex impedes the system's ability to improve performance and should not be used. Double-check each Cisco WAE interface as well as the port configuration on the adjacent device (router, switch, firewall, WAE) to verify that full-duplex is configured.
Examples
The following example shows how to set an interface bandwidth to 1000 Mbps:
WAE(config-if)# bandwidth 1000
The following example shows how to restore default bandwidth values on an interface:
WAE(config-if)# no bandwidth

(config-if) cdp
To enable the Cisco Discovery Protocol (CDP) on a particular interface on a WAAS device, rather than on all interfaces, use the cdp command in interface configuration mode.
cdp enable
Syntax Description
enable |
Enables CDP on an interface. |
Defaults
No default behavior or values
Command Modes

Device Modes
application-accelerator
central-manager
Usage Guidelines
Using the cdp enable command in global configuration mode enables CDP globally on all the interfaces of the WAAS device. If you want to control CDP behavior per interface, then use the cdp enable command in interface configuration mode.
Note Enabling CDP at the interface level overrides the global control. However, you must enable CDP globally on the WAAS device before you enable CDP on an interface. Otherwise, the following message is displayed in the command output:
WAE(config-if)# cdp enable
Cannot enable CDP on this interface, CDP Global is disabled
Examples
The following example enables CDP on Gigabit Ethernet interface (slot 1/port 0) of the WAAS device:
WAE(config)# enable interface GigabitEthernet 1/0
WAE(config-if)# cdp enable

(config-if) failover timeout
To set the maximum time for the inline interface to transition traffic to another port after a failure event, use the failover timeout command. To disable this function, use the no form of this command.
failover timeout {1 | 3 | 5}
Syntax Description
1 |
Specifies the number of seconds to a failover. |
3 |
Specifies the number of seconds to a failover. |
5 |
Specifies the number of seconds to a failover. |
Defaults
The default is 1 second.
Command Modes
interface configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
The failover timeout command is used in inlineGroup interface scope. It sets the maximum time (in seconds) for the inline interface to transition to a fail-to-wire mode of operation after a failure event occurs (such as a power outage and kernel crash). For example, if the timeout is set to 3 seconds, traffic is dropped for a maximum of 3 seconds after the WAE loses power or suffers a kernel crash. After this time, all traffic received on either port of the group interface is sent out of the other port in the group. The default timeout is 1 second.
Examples
The following example sets the failover time limit for the inline group 0 of the adapter that is installed in slot 1 to 5 seconds and then removes that setting:
(config)# interface inlineGroup 1/0
(config-if)# failover timeout 5
(config-if)# no failover timeout 5

(config-if) full-duplex
To configure an interface for full-duplex operation on a WAAS device, use the full-duplex interface configuration command. To disable this function, use the no form of this command.
full-duplex
Syntax Description
This command has no arguments or keywords.
Defaults
No default behavior or values
Command Modes
interface configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
Use this EXEC command to configure an interface for full-duplex operation. Full duplex allows data to travel in both directions at the same time through an interface or a cable. A half-duplex setting ensures that data only travels in one direction at any given time. Although full duplex is faster, the interfaces sometimes cannot operate effectively in this mode. If you encounter excessive collisions or network errors, configure the interface for half duplex rather than full duplex.
Note We strongly recommend that you do not use half-duplex connections on the WAE or on routers, switches, or other devices. Use of half-duplex impedes the system's ability to improve performance and should not be used. Double-check each Cisco WAE interface as well as the port configuration on the adjacent device (router, switch, firewall, WAE) to verify that full-duplex is configured.
Examples
The following example configures full-duplex operation on a Gigabit Ethernet interface in slot 1/port 0:
WAE(config)# interface GigabitEthernet 1/0
WAE(config-if)# full-duplex
The following example disables full-duplex operation:
WAE(config-if)# no full-duplex

(config-if) inline
To enable inline interception for an inlineGroup interface, use the inline interface configuration command. To disable inline interception, use the no form of this command.
inline [vlan {all | native | vlan_list}]
Syntax Description
vlan |
(Optional) Modifies the VLAN list parameters. |
all |
Applies the command to all tagged and untagged packets. |
native |
Specifies untagged packets. |
vlan_list |
List of VLAN IDs to either allow or restrict on this interface. A comma (,) is used to separate list entries. A hyphen (-) is used to specify a range of VLAN IDs. The valid range is 0 to 4095. |
Defaults
The default is enabled for all VLANs if you have a WAE inline network adapter installed.
Command Modes
interface configuration
Device Modes
application-accelerator
central-manager
Usage Guidelines
The inline command is used in inlineGroup interface scope. It enables or disables inline interception. If the VLAN list is omitted, the command applies to all VLAN tagged or untagged packets.You can restrict the inline feature to any specified set of VLANs.
The VLAN list can be "all" or a comma-separated list of VLAN IDs or ranges of VLAN IDs. The special VLAN ID "native" can be included to specify untagged packets.
Note When inline inspection is active, you cannot configure WCCP until you explicitly disable the inline capability on all VLANs. Conversely, you cannot enable inline interception on any inline groups until you disable WCCP.
Examples
The following example shows how to enable inline interception for all untagged and tagged packets with any VLAN ID received on ports in inlineGroup 0 of the adapter that is installed in slot 1:
(config)# interface inlineGroup 1/0
The following example shows how to disable inline interception on the same ports for 802.1Q-encapsulated packets that have the VLAN ID 5 or any VLAN ID between 10 and 15, inclusive. If the two VLANs are combined in the given order, inline interception is performed for all packets received on ports in group 0 of slot 1, except those on VLANs 5, 10, 11, 12, 13, 14 and 15.
(config)# interface inlineGroup 1/0
(config-if)# no inline vlan 5,10-15
The following example shows how to enable inline interception for all untagged traffic and traffic only on VLANs 0 through 100 on the ports in group 1 in slot 2:
(config)# interface inlineGroup 2/1
(config-if)# no inline vlan 101-4095
The following example shows how to enable inline interception for traffic only on VLAN 395 on the ports in group 1 in slot 2. Because the default behavior is to enable traffic on all VLANs, you must first disable all VLANs, then enable just the set that you want.
(config)# interface inlineGroup 2/1
(config-if)# no inline vlan all
(config-if)# inline vlan 395

Usage Guidelines
Use this command to set or change the IP address, subnet mask, or DHCP IP address negotiation of the network interfaces of the WAAS device. The change in the IP address takes place immediately.
The ip address interface configuration command allows configuration of secondary IP addresses for a specified interface as follows.
WAE(config-if)# ip address ip_address netmask [secondary]
Up to four secondary IP addresses can be specified for each interface. The same IP address cannot be assigned to more than one interface. The secondary IP address becomes active only after a primary IP address is configured. The following command configures the primary IP address.
WAE(config-if)# ip address ip_address netmask
The secondary IP addresses are disabled when the interface is shut down, and are enabled when the interface is brought up.
Use the no form of the command to disable a specific IP address.
WAE(config-if)# no ip address ip_address netmask
Note No two interfaces can have IP addresses in the same subnet.
Use the ip-address dhcp command to negotiate a reusable IP address from DHCP.
Examples
The following example shows how to configure the port channel interface with an IP address of 10.10.10.10 and a netmask of 255.0.0.0:
WAE(config)# interface PortChannel 2
WAE(config-if)# ip address 10.10.10.10 255.0.0.0
The following example deletes the IP address configured on the interface:
WAE(config-if)# no ip address
The following example enables an interface for DHCP:
WAE(config-if)# ip address dhcp
The following example configures a client identifier and hostname on the WAAS device to be sent to the DHCP server:
WAE(config-if)# ip address dhcp client-id myclient hostname myhost

Usage Guidelines
You can configure one or more interfaces to act as a backup interface (a standby interface) for another interface on a WAAS device. This feature is called "standby interface support." Standby groups, which are logical groups of interfaces, are used to implement this feature. When an active network interface fails (because of cable trouble, Layer 2 switch failure, high error count, or other failures) and that interface is part of a standby group, a standby interface can become active and take the load off the failed interface.
There must be at least two interfaces in a standby group. Interfaces that are part of a standby group are called "member interfaces." After you create a standby group, you define which interfaces should be assigned to this logical group. As part of defining the member interfaces, you specify the priority of each member interface in a standby group. The member interface with the highest assigned priority is the active interface for that particular standby group. If the active interface fails, the operational member interface with the next highest priority in the standby group comes up, and so forth. If all member interfaces of a particular standby group are down and then one of the member interfaces comes up, the WAAS software detects this situation and brings up the standby group on the member interface that just came up.
The failure or failover of member interfaces within a standby group triggers alarms and traps (if alarms and traps are enabled on the WAAS device). Alarms are sent out when failover occurs between member interfaces in a standby group. Specifically, minor alarms are sent out when member interfaces fail, and these alarms are cleared automatically when the interface failover has been successfully completed. Major alarms are sent out if the standby group goes down (that is, no member interface in a standby group can be brought up.)
Note A physical interface can belong to more than one standby group. Consequently, a single interface can act as a standby interface for more than one standby group.
To configure standby interfaces, interfaces are logically assigned to standby groups. The following rules define the standby group relationships:
•Each standby group is assigned a unique standby IP address, shared by all member interfaces of the standby group. The IP address of the standby group is shared among the member interfaces; however, only the active interface of the standby group uses this shared IP address at any one time. This shared IP address is configured as an alias on the active interface.
•Configure the duplex and speed settings of the member interfaces for better reliability.
•If all the member interfaces of a standby group fail and then one recovers, the WAAS software brings up the standby group on the operational member interface.
•If a physical interface is a member of a port channel group, it cannot join a standby group. Likewise, if a physical interface is a member of a standby group, it cannot join a port channel group.
•A standby group comprises two or more interfaces.
•The maximum number of standby groups on a WAAS device is four.
Note Interface IP addresses and standby group IP addresses must be on different subnets to ensure reliable operation. You can use dummy IP addresses in the private address space to serve as interface primary IP addresses, and use the real WAAS device's IP address to serve as the standby group IP address in a different subnet to satisfy this requirement. When dummy IP addresses are used, these interface IP addresses serve only as substitutes to bring up the interface. For example, the WAAS device's interface requires an IP address on an interface for initialization. Make sure to configure the interface default gateway using the ip default-gateway global configuration command instead of the ip route command.
•Each interface in a standby group is assigned a priority. The operational interface with the highest priority in a standby group is the active interface. Only the active interface uses the group IP address.
•The priority of an interface in a standby group can be changed at runtime. The member interface that has the highest priority after this change becomes the new active interface (the default action is to preempt the currently active interface if an interface with higher priority exists).
•The maximum number of errors allowed on the active interface before the interface is shut down and the standby is brought up is configured with the errors option, which is disabled by default.
Tip If an interface belongs to more than one standby group, you can configure the interface with a different priority in each standby group for better load-balancing. For example, interfaces Gigabit Ethernet 1/0 and Gigabit Ethernet 2/0 are both in standby group 1 and in standby group 2. If you configure Gigabit Ethernet 1/0 with the highest priority in standby group 1 and configure Gigabit Ethernet 2/0 with the highest priority in standby group 2, standby group 1 uses Gigabit Ethernet 1/0 as the active interface, while standby group 2 uses Gigabit Ethernet 2/0 as the active interface. This configuration allows each interface to back up the other one, if one of them fails.
Note Unlike port channels, standby groups do not support IP ACLs at a group level. However, you can configure a member interface of a standby group to support an IP ACL at the interface level. For example, you can individually configure the two member interfaces of Standby Group 1 (the Gigabit Ethernet slot 1/port 0 interface and the Gigabit Ethernet slot 2/port 0 interface) to support an IP ACL named ACL1, but you cannot configure the Standby Group 1 to support ACL1.
Examples
The following example configures two Gigabit Ethernet interfaces to be part of the same standby group, with interface 1/0 as the active interface:
WAE(config-if)# interface gigabitEthernet 1/0 standby 1 ip 10.16.10.10 255.255.254.0
WAE(config-if)# interface gigabitEthernet 2/0 standby 1 ip 10.16.10.10 255.255.254.0
WAE(config-if)# interface gigabitEthernet 1/0 standby 1 priority 300
WAE(config-if)# interface gigabitEthernet 2/0 standby 1 priority 200
WAE(config-if)# interface gigabitEthernet 1/0 standby 1 errors 10000
WAE(config-if)# interface gigabitEthernet 2/0 standby 1 errors 10000
The following example displays information about the standby group configuration by entering the show standby EXEC command. In the following sample command output, one standby group (Standby Group 1) is configured on this WAAS device. The command output also shows which member interface is the active interface. In this case, the active interface is the Gigabit Ethernet slot 1/port 0 interface.
Description: This a backup for Gigabit Ethernet 2/0.
IP address: 10.16.10.10, netmask: 255.0.0.0
Active interface: Gigabit Ethernet 1/0
Maximum errors allowed on the active interface: 500
Note To display information about a specific standby group configuration, enter the show interface standby group_number EXEC command.
The following example creates a standby group, Standby Group 1:
WAE(config)#
interface standby 1
The following example assigns a group IP address of 10.10.10.10 and a netmask of 255.0.0.0 to Standby Group 1. You can configure a group IP address regardless of whether the standby group is shut down or not.
WAE(config-if)#
ip address 10.10.10.10 255.0.0.0
WAE(config-if)#
errors 500
The following example shows how to add two Gigabit Ethernet interfaces to Standby Group 1 and then assign each of these member interfaces a priority within the group:
a. First a Gigabit Ethernet interface (slot 1/port 0) is added to Standby Group 1 and assigned a priority of 150.
WAE(config)#
interface gigabitEthernet 1/0
WAE(config-if)#
standby 1 priority 150
b. Next, a second Gigabit Ethernet interface (slot 2/port 0) is added to Standby Group 1 and assigned a priority of 100 (the default value).
WAE(config)#
interface gigabitEthernet 2/0
WAE(config-if)#
standby 1
Because GigabitEthernet 0/0 is assigned the highest priority (a priority number of 150) of all the member interfaces in the group, it is chosen as the active interface for the group if it can be brought up.
The following example removes the GigabitEthernet slot 1/port 0 interface from Standby Group 1 using the no form of the standby command:
